1. Versions: Nakama {3.5}, {Linux}

Hello All, I succesfully upgraded nakama from 3.9.0 to 3.15.0, And after complete upgradae & database migrate, having the following error popping in the console

{“level”:“error”,“ts”:“XXXXX”,“caller”:“server/console.go:346”,“msg”:“Error querying storage collections.”,“error”:“ERROR: syntax error: unimplemented: unimplemented at or near "select" (SQLSTATE 0A000)”}

Couldn’t figure out this one & reaching out community here.  
Thanks in advance

Hello @voxel456,

Are you running CRDB? If yes, what version?

Thank you!  
That was the issue.. I was on Cockroach DB v19.. Then after your reponse, i looked into documentation & found that minimum version is 20. So I upgraded cockroach. Problem solved 🙂
